Description

Technical Field

[0001] The utility model relates to an automatic conveyor line, in particular to a rotary conveying mechanism. Background Art

[0002] Automatic conveying structures have been widely used in existing automatic production lines. According to the conveying requirements, a conveying mechanism with the head and tail connected is often needed to facilitate the cyclic movement of the carrier under the action of the conveying mechanism, so as to facilitate the cyclic utilization of a group of carriers in sequence. In order to reduce the space requirement, there is currently a conveying mechanism. After the carrier reaches one end of the horizontal track, it flips in the vertical plane along with the conveying structure, enters another horizontal track below, and after reaching the other end of the horizontal track below, it flips back to the upper horizontal track again. At this time, the track is integrally circular and arranged in the vertical direction.

[0003] Although the above structure has the advantage of saving space, however, since the center of gravity of the carrier is unstable during flipping and the track direction changes greatly, the carrier is prone to jamming, which is not conducive to the normal operation of the conveying mechanism. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rotary conveying mechanism that is not prone to jamming.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rotary conveying mechanism, comprising:

[0007] A track having a first straight segment, a second straight segment, and a rotary segment connecting between the first straight segment and the second straight segment, the rotary segment being longitudinally arranged, and the height of the first straight segment being higher than that of the second straight segment;

[0008] A conveyor belt running along the track, and the conveyor belt having opposite first conveying surface and second conveying surface;

[0009] A sliding member having a chute recessed into the sliding member on the side surface, and a part of the conveyor belt is embedded in the chute. The chute has opposite supporting surface and abutting surface. When the supporting surface supports the first conveying surface of the conveyor belt, and the abutting surface is adjacent to the second conveying surface of the conveyor belt, the sliding member is displaced along the track as the conveyor belt runs;

[0010] A rotary structure having a mating surface parallel to the rotary segment of the track. When the sliding member is located at the rotary segment of the track, the rotary structure abuts against the bottom of the sliding member, so that the abutting surface of the sliding member abuts against the second conveying surface of the conveyor belt.

[0011] Optionally, the rotary structure is configured to be circular and rotate along its central axis.

[0012] Optionally, the rotary structure further includes a protrusion, the protrusion is connected to the mating surface, and has a pushing surface away from the mating surface, and the pushing surface of the protrusion is connected to the mating surface through a compression spring.

[0013] Optionally, the rotary structure includes:

[0014] A top cover, having a cover plate portion and a central axis portion, the cover plate portion is configured to be circular ring-shaped, the central axis portion is configured to be a circular tubular shape with both ends open, and one end of the central axis portion is connected to the inner circle of the cover plate portion and perpendicular to the cover plate portion;

[0015] A limit shell, having an inner ring portion and an outer ring portion that are coaxially arranged and are both configured to be circular tubular shapes, and a connecting portion connected between the inner ring portion and the outer ring portion. The inner ring portion is coaxially sleeved outside the central axis portion, and a plurality of first through holes are provided thereon. The diameter of the outer ring portion is matched with the cover plate portion of the top cover, and the outer wall of the outer ring portion is the mating surface. A plurality of second through holes corresponding to the first through holes one by one are provided on the outer ring portion;

[0016] A bottom cover, configured to be an annular structure, and its inner circle is connected to one end of the central axis portion of the top cover away from the cover plate portion;

[0017] A telescopic assembly, including a spring member and a telescopic column. The spring member is a compression spring, one end of which abuts against the outer wall of the central axis portion of the top cover, and the other end is connected to the telescopic column. The telescopic column passes through any set of corresponding first through holes and second through holes, and the end of the telescopic column away from the spring member is the protrusion.

[0018] Optionally, the diameter of the spring member is greater than the diameter of the first through hole.

[0019] Optionally, the telescopic column further includes a sliding portion, the sliding portion is configured to be cylindrical, its diameter is less than or equal to the diameter of the first through hole and greater than the diameter of the second through hole. The protrusion is coaxially connected to one end of the sliding portion away from the spring member, and the diameter of the protrusion is less than or equal to the diameter of the second through hole.

[0020] Optionally, the rotary structure further includes a filling frame, the filling frame is filled between the limit shell and the central axis portion of the top cover, and a spring groove matching the spring member is formed between the first through hole and the outer wall of the central axis portion of the top cover, and the spring groove is used to accommodate the spring member.

[0021] Optionally, a plurality of the protrusions are arranged in a circumferential array to form a group, and adjacent two groups of the protrusions are arranged in a staggered manner.

[0022] Optionally, a plurality of positioning surfaces are formed on the outer wall of the central axis portion of the top cover. The positioning surfaces are flat surfaces and correspond to the plurality of spring members respectively, and each of the spring members abuts against the positioning surface.

[0023] Optionally, the abutting surface of the sliding member is configured to cooperate with the curved surface of the turning section of the track.

[0024] The beneficial effects of the utility model are as follows: when the sliding member enters the turning section of the track, the turning structure abuts against the sliding member, so that the abutting surface of the sliding member abuts against the conveyor belt, increasing the friction force between the sliding member and the conveyor belt, so that the sliding member moves along with the operation of the conveyor belt, thereby reducing the risk of jamming of the sliding member when passing through the turning section of the track.

[0025] Further, the circular turning structure rotates along its central axis, converting the frictional force between the turning structure and the sliding member into rolling frictional force, which helps to improve the smoothness of the movement of the sliding member.

[0026] Further, the pushing surface and the mating surface of the protruding portion of the turning structure are connected by a compression spring, so that there is a certain floating space for the distance between the sliding member and the mating surface, preventing excessive pressure or gaps between any sliding member and the conveyor belt caused by structural errors, improving the universality of the conveying mechanism, and helping to improve the smoothness of the movement of the sliding member.

[0027] Further, the direction of the telescopic column is restricted by the first through hole and the second through hole, preventing the telescopic column from shifting under the action of pressure and friction force.

[0028] Further, by adjusting the diameter, the spring member cannot enter the limiting shell through the first through hole, which helps to restrict the compression spring and prevent the compression spring from falling off.

[0029] Further, by adjusting the diameter, the sliding part cannot extend out of the limiting shell through the second through hole, preventing the telescopic column from coming out, and helping to keep the positions of the pushing surfaces on the same circular arc.

[0030] Further, a spring groove is formed by the filling frame, preventing the spring member from bending laterally under pressure, which helps to protect the structure of the spring member.

[0031] Further, since the telescopic assemblies are arranged along the radial direction of the turning structure, the distance between two adjacent pushing surfaces in the same telescopic assembly is relatively far, and they are arranged in multiple telescopic assemblies and are staggered, which helps to improve the abutting ability of the turning structure against the sliding member.

[0032] Further, the position where the spring member abuts against the outer wall of the central axis portion of the top cover is configured as a flat surface, which is convenient for installation and positioning, and helps to protect the structure of the spring member.

[0033] Further, the contact surface of the sliding member is fitted to the rotary section of the track, increasing the contact area and thus further increasing the frictional force.

[0044] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the rotary conveying mechanism protected by the present utility model application includes a track, a conveyor belt, a sliding member 2 and a rotary structure 3. The track has a first straight section 11 with a relatively high height, a second straight section with a relatively low height, and a longitudinally arranged rotary section 12 connected between the first straight section 11 and the second straight section. The conveyor belt runs along the track, and its two sides are respectively a first conveying surface and a second conveying surface. The sliding member 2 is displaced along with the running of the conveyor belt under the action of friction. A chute 25 recessed into the sliding member 2 is formed on its side surface. Relative supporting surfaces 251 and abutting surfaces 252 are provided in the chute 25. When the sliding member 2 is located on the first straight section 11 of the track, the supporting surface 251 supports on the first conveying surface of the conveyor belt, and the abutting surface 252 is adjacent to the second conveying surface of the conveyor belt. The rotary structure 3 has a mating surface 325 parallel to the rotary section 12 of the track. When the sliding member 2 is located on the rotary section 12 of the track, the rotary structure 3 abuts against the bottom of the sliding member 2, so that the abutting surface 252 of the sliding member 2 abuts against the second conveying surface of the conveyor belt.

[0046] When the sliding member 2 enters the rotating section 12 of the track, the rotating structure 3 contacts the sliding member 2, causing the contact surface 252 of the sliding member 2 to contact the conveyor belt, thereby increasing the friction between the sliding member 2 and the conveyor belt, so that the sliding member 2 moves with the operation of the conveyor belt, thereby reducing the risk of the sliding member 2 getting stuck when passing through the rotating section 12 of the track.

[0047] Please refer to the following examples for details.

[0048] Embodiment 1:

[0049] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The rotary conveying mechanism shown in a preferred embodiment of the present application includes a track, a conveyor belt and a sliding member 2. The conveyor belt runs along the track, and the sliding member 2 is supported on the conveyor belt and moves with the running of the conveyor belt through the friction between the conveyor belt and the conveyor belt.

[0050] The track includes a first straight segment 11, a second straight segment and two revolving segments 12. The first straight segment 11 and the second straight segment are both formed by two rectangular long strip frames 101 arranged opposite to each other. The two frames 101 are arranged vertically and flush with each other. Two horizontal long strip transverse grooves are formed on the side of any frame 101 facing the other frame 101, and the lengths of the two transverse grooves are the same as those of the frame 101. The two transverse grooves with the same height above form the first straight segment 11 of the track, and the two transverse grooves with the same height below form the second straight segment of the track. The two revolving segments 12 are respectively connected between the two ends of the first straight segment 11 and the second straight segment, so that the track forms a closed structure connected end to end. The revolving segment 12 of the track is formed by four driving wheels 102 with the same structure. The driving wheel 102 is a sprocket that is tangent to the first straight segment 11 and the second straight segment of the track. The two ends of each frame plate 101 correspond to two driving wheels 102, and the top positions of the two driving wheels 102 match the two ends of the transverse groove of the first straight segment 11, thereby forming two semicircular rotating segments 12, connecting the end of the first straight segment 11 with the end of the second straight segment. The four driving wheels 102 rotate synchronously and controllably along the central axis.

[0051] The conveyor belt includes two chain conveyor belts, which have strong support force in the width direction. One side of the two chain conveyor belts is respectively embedded in a horizontal groove on a frame plate 101, forming a conveyor belt with a hollow middle portion. The top surface of the part of the conveyor belt supported on the first straight section 11 of the track is the first conveying surface, and the bottom surface is the second conveying surface. The second conveying surface of the conveyor belt is hinged to the driving wheel 102, so that the conveyor belt runs along the track under the drive of the driving wheel 102.

[0052] The sliding member 2 includes a carrier plate 21, and a structural block 24, a first abutting block 23, a partition block 22, and a second abutting block 26 that are all connected to the bottom surface of the carrier plate 21. The carrier plate 21 is configured as a rectangular plate, with the direction of its longer side as the length direction and the direction of its shorter side as the width direction. The structure above the carrier plate 21 is adapted to the workpiece being conveyed, and a long strip-shaped partition block 22 is fixedly connected to the bottom. The direction of the partition block 22 is parallel to the length direction of the carrier plate 21 and is equal to the length of the carrier plate 21. Two structural blocks 24 are symmetrically arranged on both sides of the partition block 22. The structural blocks 24 are arranged between the partition block 22 and the edge of the carrier plate 21 and are adjacent to the middle of the partition block 22. The two first abutting blocks 23 are axisymmetric with respect to the partition block 22, are respectively connected to the ends of the structural blocks 24 far from the carrier plate 21, are horizontally arranged and parallel to the width direction of the carrier plate 21, and extend in a direction away from the partition block 22. The second abutting block 26 is arranged between the partition block 22 and the structural block 24, is parallel to the length direction of the carrier plate 21 and has a height less than that of the partition block 22 and the structural block 24, forming a structure with a concave middle part. The carrier plate 21 and a group of structural blocks 24 and first abutting blocks 23 together form a chute 25. The ends of the two chain conveyor belts far from the frame plate 101 respectively extend into the two chutes 25. The bottom surface of the carrier plate 21 serves as the supporting surface 251 of the chute 25, and the surface of the first abutting block 23 close to the carrier plate 21 serves as the abutting surface 252 of the chute 25. When the sliding member 2 is located on the first straight section 11 of the track, the supporting surface 251 of the chute 25 supports on the first conveying surface of the conveyor belt, and the abutting surface 252 of the chute 25 is adjacent to the second conveying surface of the conveyor belt and the distance is small. When the sliding member 2 is transferred to the second straight section of the track, the abutting surface 252 of the chute 25 supports on the second conveying surface of the conveyor belt. The abutting surface 252 of the chute 25 is configured as an arc shape adapted to the turning section 12 of the track, which helps to increase the contact area between the abutting surface 252 of the chute 25 and the conveyor belt and increase the friction.

[0053] The rotary conveying mechanism in this utility model further includes four rotary structures 3 configured in a wheel-like structure. The rotary structures 3 and the driving wheel 102 are coaxially arranged in pairs and rotate synchronously. When the sliding member 2 is transferred to the rotary section 12 of the track, the two rotary structures 3 respectively abut against the bottom surfaces of the two second abutting blocks 26, causing the abutting surface 252 of the chute 25 to abut against the second conveying surface of the conveyor belt, thereby increasing the friction between the sliding member 2 and the conveyor belt, and helping to stabilize the center of gravity of the slider, preventing the slider from shaking, so as to keep the slider moving stably with the conveyor belt and reducing the risk of jamming. Since the second abutting block 26 is recessed between the structural block 24 and the partition block 22 to form a rotary groove that fits the rotary structure 3, it helps to maintain the position of the sliding member 2 in the vertical direction when the sliding block flips, preventing the sliding block from shifting significantly, improving the stability during the flipping of the slider, and reducing the risk of the slider falling off or jamming. Two rotary structures 3 are provided in the same rotary section 12 and the two rotary grooves are symmetrically arranged, which helps to balance the center of gravity and improve the stability.

[0054] Please refer to Figure 5 , the rotary structure 3 includes a top cover 31, a limit shell 32, a bottom cover 33 and a telescopic assembly 34.

[0055] The top cover 31 includes a cover plate portion 311 and a central shaft portion 312 connected to each other. The cover plate portion 311 is configured as a circular plate shape with a hollow middle. The central shaft portion 312 is configured as a circular tube shape, coaxially arranged with the cover plate portion 311 and connected to the cover plate portion 311 at one end, so that a shaft hole is formed in the middle of the top cover 31. The shaft hole is integrally cylindrical and has a rectangular groove formed on one side, which is convenient for the shaft fitting in the shaft hole to be relatively fixed with the shaft hole, thereby driving the whole rotary structure 3 to rotate. Sixteen positioning surfaces 313 are formed on the outer wall of the central shaft portion 312 of the top cover 31. Each positioning surface 313 is configured as a plane with the same structure and is evenly arranged along the circumference at the same height of the central shaft portion 312.

[0056] The top cover 31 further includes a frustum portion configured as an annular shape, connected to the cover plate portion 311 and located on the same side as the central shaft portion 312, and the diameter of its outer circle is smaller than that of the cover plate portion 311 and larger than that of the central shaft portion 312. The height of the frustum portion of the top cover 31 is smaller than that of the central shaft portion 312.

[0057] The limit shell 32 includes an inner ring part 321, an outer ring part 323 and two connecting surfaces. The inner ring part 321 and the outer ring part 323 are configured as circular tubes with the same height and coaxial. The two circular connecting surfaces are respectively connected between the two ends of the inner ring part 321 and the two ends of the outer ring part 323, so that the whole limit shell 32 forms a hollow circular ring-shaped box structure. The whole limit shell 32 is coaxially sleeved on the frustum part of the top cover 31, so that there is a separation between the inner ring part 321 of the limit shell 32 and the central axis part 312 of the top cover 31, and the connecting part 326 of the limit shell 32 is connected to the cover plate part 311 of the top cover 31. Sixteen first through holes 322 are formed on the inner ring part 321 of the limit shell 32, with eight first through holes 322 as a group, and a total of two groups. The first through holes 322 in the same group are evenly arranged along the same circumference, and the two groups of first through holes 322 are arranged in a staggered manner, so that each first through hole 322 corresponds to the positioning surface 313 of the top cover 31. Two groups of second through holes 324 corresponding to the first through holes 322 one by one are formed on the outer ring part 323 of the limit shell 32, and the diameter of the second through holes 324 is smaller than the diameter of the first through holes 322. The outer surface of the limit shell 32 is the mating surface 325 of the rotary structure 3.

[0058] The bottom cover 33 is integrally configured as a circular ring, and includes an embedded part 331 and a fixing part 332 which are connected to each other and coaxially arranged. The embedded part 331 of the bottom cover 33 is embedded between the limit shell 32 and the central axis part 312 of the top cover 31 to prevent the limit shell 32 from shifting. The shape of the inner circle of the fixing part 332 of the bottom cover 33 is matched with the shaft hole, and is fixedly connected to one end of the central axis part 312 of the top cover 31 away from the cover plate part 311, clamping the limit shell 32 between the cover plate part 311 of the top cover 31 and the bottom cover 33. The diameter of the outer circle of the fixing part 332 of the bottom cover 33 is slightly smaller than the diameter of the embedded part 331.

[0059] The telescopic assembly 34 includes a spring member 341 and a telescopic column 342. The spring member 341 is a compression spring, with one end connected to and abutting against the positioning surface 313 of the top cover 31, and the other end fixedly connected to the telescopic column 342. The length of the spring member 341 is adapted to the distance between the central axis portion 312 of the top cover 31 and the inner ring portion 321 of the limit shell 32. The diameter of the spring member 341 is larger than the diameter of the first through hole 322, so that the spring member 341 cannot enter the interior of the limit shell 32. The telescopic column 342 includes a sliding portion 343 and a protruding portion 344 that are both configured as cylinders. The sliding portion 343 and the protruding portion 344 are coaxially arranged. One end of the sliding portion 343 is directly connected to the spring member 341, and the protruding portion 344 is connected to the end of the sliding portion 343 away from the spring member 341. The length of the sliding portion 343 is adapted to the width of the limit shell 32. The diameter of the sliding portion 343 is slightly smaller than the diameter of the first through hole 322 and larger than the diameter of the second through hole 324. The diameter of the protruding portion 344 is slightly smaller than the diameter of the second through hole 324, so that the sliding portion 343 is embedded in the limit shell 32, and the protruding portion 344 extends out from the second through hole 324. The side surface of the protruding portion 344 away from the spring member 341 is a pushing surface 345. When the sliding member 2 reaches the turning section 12 of the track, the bottom surface of the second abutting block 26 of the sliding member 2 contacts the pushing surface 345 of the telescopic assembly 34. At this time, the spring member 341 elastically supports the pushing surface 345, so that the abutting surface 252 of the sliding groove 25 supports on the second conveying surface of the conveyor belt, improving the stability of the sliding member 2 during flipping. Since there is a certain elastic space in the distance between the pushing surface 345 and the mating surface 325, it helps to compensate for the structural errors of each component and improve the universality of the overall turning structure 3 and the rotary conveying mechanism.

[0060] In this embodiment, the rotary structure 3 further includes a filling frame 35 embedded between the limiting shell 32 and the central axis portion 312 of the top cover 31, which is used to form an internal channel for accommodating the spring member 341 inside the limiting shell 32, so as to restrict the telescopic direction of the spring member 341. Eight semi-circular grooves 353 extending along the radial direction and evenly arranged are formed on the side surface of the frustum portion of the top cover 31 away from the cover plate portion 311. The positions of the semi-circular grooves 353 correspond to a group of first through holes 322 of the limiting shell 32 close to the cover plate portion 311 of the top cover 31 one by one, and the diameter of the semi-circular grooves 353 is matched with the diameter of the spring member 341. The filling frame 35 is embedded between the limiting shell 32 and the central axis portion 312 of the top cover 31, and its overall structure is configured to be annular and match the limiting shell 32, and has an annular first bottom surface 351 and a second bottom surface 352. The first bottom surface 351 of the filling frame 35 is connected to the frustum portion of the top cover 31, and eight semi-circular grooves 353 matching the frustum portion of the top cover 31 are formed thereon, so as to form a circular internal channel. Eight semi-circular grooves 353 extending along the radial direction are also formed on the second bottom surface 352 of the filling frame 35, and the semi-circular grooves 353 on the second bottom surface 352 of the filling frame 35 have the same structure as those on the first bottom surface 351 but in the opposite direction, and the positions are matched with a group of first through holes 322 of the limiting shell 32 away from the cover plate portion 311 of the top cover 31. The side surface of the embedded portion 331 of the bottom cover 33 away from the fixing portion 332 is connected to the second bottom surface 352 of the filling frame 35, and eight semi-circular grooves 353 matching the second bottom surface 352 of the filling frame 35 are formed thereon, so as to form another eight circular internal channels. The sixteen internal channels are respectively used to accommodate the spring members 341 of the sixteen sets of telescopic components 34, prevent the spring members 341 from being bent by force, thereby protecting the structure of the spring members 341 and extending the service life.

[0061] The support slider 2 is pushed by the rotary structure 3 to keep each slider 2 moving along the same route every time it passes through the rotary section 12 of the track, which helps to improve the stability of the movement of the slider 2 and reduce the risk of jamming.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0063] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
